What is the reason for the small yellow bulb warning light on the Sagitar dashboard?
2 Answers
Dashboard bulb fault light, lighting alarm light. Lights on the vehicle: Turn signals, brake lights, license plate lights, width indicator lights, front and rear fog lights, reverse lights, high beam headlights, low beam headlights, etc. Possible causes of the fault: Loose connections in the wiring, affecting the resistance value of the lighting circuit, causing the dashboard computer to mistakenly identify the bulb as faulty; poor wiring contact; bulb filament is partially broken. Solution: Park the car in a safe place, turn off the engine, and use a wrench to remove the negative terminal of the battery. Wait for 15 seconds and then reconnect it to see if the warning light disappears. If it is still on, it is recommended to immediately go to a 4S store or a professional auto repair shop to have a technician read the fault code with a scanner.
When driving my Sagitar, I noticed the small yellow warning light on the dashboard was on. This is mostly caused by a burnt-out bulb, most commonly the rear brake light or taillight. Volkswagen models are particularly prone to this issue. Last time, I fixed it by replacing the brake light bulb myself. Sometimes, poor electrical contact can also trigger false alarms, such as loose connectors or rust caused by water ingress. I recommend first checking the light sockets near the trunk lid—just unscrew them to inspect. If the bulbs are fine, then check the fuses, located in the fuse box under the steering wheel on the left side. Occasionally, the lighting control system might glitch, causing sensor false alarms, though this is rare. The key is not to ignore it—driving at night without lights is extremely dangerous. If you can’t fix it yourself, take it to a repair shop immediately and have them inspect the entire electrical system to prevent bigger issues. This problem is so common that experienced drivers all know about it.
